How to learn Spring?

Hi everyone,
I have experience on Java , JSP and Servlet. Want to know how to upgrade to next level.
1.Do I need to learn Spring and Struts togerther? Any good book or resource in the net?
2. EJB 3 or Spring which one is more market value?
Thanks

> 1.Do I need to learn Spring and Struts togerther?
No.
Any good book or resource in the net?
Pro Spring
Spring in Action

>2. EJB 3 or Spring which one is more market value?
A search on Dice.com showed roughly the same number of available positions for both. If that's a valid measure of "market value", they seem about even.

  • Learn spring framework from scrach

    hi, all
    i m new to spring, is there any good book for people like me to learn Spring?
    i currently have a 'Manning, Spring In Action' 2nd edition(2007), but i found it's quite confusing coz the sample code in the book is not very clear and helpful.
    could u guys tell me how you learned Spring?
    Any help will be sincerely appreciated!
    Thanks!
    regards

    Sorry, didn't read your post carefully, maybe a Wrox Book : "Beginning Spring" which is more simple (I think) .

  • How to learn Indesign CS3  SDK programming for windows

    Hi,<br /><br />I am very new to plugin development.I am working in Indesign CS3 SDK (windows).<br /><br />But I am not able to write /understand the syntax of InterfacePtr.<br /><br />for eg :<br /><br />InterfacePtr<IClassIDData> orgDocFileHandlerData(doc, IID_ORGICLASSIDDATA); <br /><br />We get Pointer of any Interface , and pass some arguments .<br /><br />So can anybody help how to learn this programming , I am not finding any <br /><br />books or tutorials on this so that I can read from the basic. I have only <br /><br />referred to Programming Guide(CS3). Can anybody please help/explain  me how <br /><br />to learn it?<br /><br />Thanks.<br /><br />Ravi Sharma

    It's only my way of understanding about InDesign SDK :<br /><br />* SDK objects are know as 'boss(es)' and are accessed thru interfaces.<br />* You can imagine object as collection of interfaces. And you can even aggregate new interfaces to existing objects.<br />* When you have a reference to an interface of a boss, you can access other interfaces (of the same boss - or object) using the *amazing* syntax : (here, doc is a probably an IDocument interface on a kDocBoss object, and you want to access it's IClassIDData interface)<br />InterfacePtr<IClassIDData> orgDocFileHandlerData(doc, IID_ORGICLASSIDDATA); <br />* And finally, InterfacePtr has a reference counter, which allows the framework to destroy the interface object - not the boss of course, only the memory used by the object - when it's non mre referenced.<br /><br />HTH !

  • How to learn SBOi?

    Hi all,
        To understand/learn SBOi what is pre-requests? Do I need knowledge about Netweaver and R/3 DB structures?
        I have knowledge about SBO SDK and MS tools and developing Add-ons. What are others skill that I need to learn before starting SBOi?

    Expecting help from all you . Thanks in advance.
    With Regards
    B. Ravi Shankar

    Ravi,
    I you are asking about "how to learn about B1i", you will need have understanding with SAP Business One, R/3, the SAP Business One integration for SAP NetWeaver (B1i) and have a good knowledge of data integration in general.  With respect to SAP Business One, there are many ways to get information/knowledge on this by going to the SAP PartnerEdge Portal and clicking on the "Education" tab.  You can also read the SAP Business One online help documentation.  This type of learning couls also be done with R/3.  In both the SAP Business One and R/3 case, you would need to be an SAP Partner to get to the PartnerEdge Portal.  With respect to learning B1i, there are many whitepapers on SDN on the SAP Business One main page as well as more information on the PartnerEdge Portal.  You can also download the SAP Business One integration for SAP NetWeaver product and read through the accompanying documentation.

  • How to learn Java!!(help me!)

    I am a beginner.I've learned Java for 6 months.But I still don't konw what is Java.Can somebody tell me how to learn Java step by step?For instance,which one should I learn first,and then what to learn next?Thank you!!!!

    I've learned Java for 6 months.But I
    still don't konw what is Java.I take it by "learned Java for 6 months" you don't mean programming with it. If you've done programming with it, you should have some idea of what you're actually doing. If not, here is a basic idea of what Java IS:
    1. Java is a virtual machine (it's kind of like a "fake" operating system running on top of your own operating system (like Windows XP).
    2. Any operating system that has a copy of the Java Runtime Environment ported to it can run Java programs. This allows Java programs to be cross-platform.
    3. Java is also the name of the language used to write programs for this virtual machine.
    4. Try clicking on the Documentation link at the left of this forum for more information about Java :P

    This is a tough one.  Most config requirements come from trial and error and experience.
    You can look in SE10 and see what config the previous MM consultants have created / changed and try and piece it from there.  So SE10 find a previous MM user and see what changes they made. Then search on SAP help to understand why that config was created or changed. 
    Its a slow process and there is no quick way to learn it.  SAP academy is great but they can't tell you the whole picture as different businesses have different requirements, hence the need for consultants.
    Good luck
